 【Structure and properties】 The size of BD test paper is the same as the cross-section area of the standard test package, and the front of the paper is printed with a yellow strip pattern.
【 Application】It is specially used for testing whether the cold air in the pre-vacuum or pulsating vacuum pressure steam sterilizer or in the article bag is completely discharged and whether there is cold air in the article bag;The steam penetration test chart of air mass exists, the color of sterilization is not easy to fade.
【Cautions】
1. In general, when pipe air supply is applied, the vapor pressure of saturated steam should reach 0.4mpa to 0.6mpa, and the color change in BD test diagram is uneven when less than 0.3mpa.
2. For the pre-vacuum or pulsating vacuum pressure steam sterilizer using pipeline air supply, when the air supply is stopped for more than 2 days and used again, the cold air inside the air supply pipeline should be exhaust treatment, otherwise the saturated steam may contain a large amount of water gas, so that the cold air is not suitable for discharge.At the same time, it will cause the humidity of the item package (commonly known as the wet package), so that the BD test diagram is soaked and the test results cannot be displayed.
3. The package of articles or equipment should be packed as required, not too big or too tight.
4. Cloth towels for packing articles or instruments shall be cleaned regularly.The non-softness of the cloth will affects the exhaust of air during the pre-vacuum process and the subsequent penetration of saturated steam.It makes the color of test drawing not uniform or have local area not discoloration.
【Storage】Store at room temperature (20 ℃-30 "C) and dry (< 50% relative humidity) to avoid direct contact with sunlight
【Guarantee period】18 months from the date of production.
